We will make greater progress in the high-quality development of coal

-- Expert interpretation of the National Energy Administration on Further Accelerating the intelligent Construction of Coal Mines to Promote the high-quality development of coal

近日，The National Energy Administration issued the Notice on Further Accelerating the Intelligent Construction of Coal Mines to Promote the High-quality Development of Coal (Guonengfa Coal (2024) No. 38)，Hereinafter referred to as the Notice)，The next stage of intelligent construction of coal mine is systematically deployed，Twelve key tasks have been identified，It points out the direction for accelerating the construction of new quality coal productivity and promoting high-quality development。"Notice" pointed out，China's coal mine intelligent construction has entered a new stage of accelerated development and in-depth promotion，However, it still faces problems such as unbalanced construction progress, insufficient support for core technology and equipment, and urgent need to strengthen personnel security，We should further unify our thinking and improve our understanding，Adhere to problem-oriented, goal-oriented，We will strengthen overall planning and step by step implementation，Promote the intelligent development of coal mines to a wider range, deeper level and higher quality。

First, the intelligent construction of coal mines in China is shifting from demonstration construction to scale promotion, and it is necessary to comprehensively promote the intelligent construction of all kinds of coal mines

In February 2020, the National Development and Reform Commission, the National Energy Administration and other eight departments issued the "Guidance on Accelerating the intelligent Development of Coal Mines" (Development and Reform Energy (2020) No. 283), put forward the goals and tasks of the intelligent construction of coal mines, and then launched the first batch of intelligent demonstration coal mine construction work。Driven by the national intelligent demonstration coal mine construction, all coal-producing provinces and coal enterprises have carried out the construction of intelligent demonstration coal mines。At present, China's coal mine intelligent construction has achieved remarkable results，Breakthroughs in a number of key core technologies，Developed a number of high-end intelligent equipment，A number of innovative application scenarios have been built，A number of intelligent demonstration coal mines with advanced technology and strong leadership have been built，It shows an intelligent construction pattern led by demonstration coal mines and actively followed by other coal mines，It has accumulated experience and laid a foundation for the comprehensive promotion of intelligent construction in different types of coal mines。

Combined with the actual situation of intelligent construction of existing coal mines, the "Notice" puts forward clear requirements for promoting the intelligent construction of new coal mines, coal mines under construction and production coal mines。New coal mines are required to be designed and constructed in accordance with intelligent standards in principle, and the intelligent production system is evaluated and accepted during the joint test run and completion acceptance.The coal mine under construction should add the intelligent construction plan in time, and strive to complete the intelligent construction before the completion and operation。The production of coal mines has not only made it clear that it is necessary to focus on promoting the intelligent transformation of large coal mines and coal mines with serious disasters，It is more clear that large coal mines will build single and multiple systems intelligent by the end of 2025，With conditions to achieve intelligent mining system，Coal mines with severe disasters and production coal mines with altitudes higher than 2,400 meters or mining depths greater than 600 meters，According to geological conditions and disaster characteristics, one mine and one policy should formulate intelligent transformation plan，Accelerate the intelligent transformation of key hazardous links;Especially for large and above accidents in coal mines，Before resuming production, it is necessary to formulate intelligent construction plans，Clear deadline，Built within the required time limit。

Second, China's coal mines are widely distributed and the geological conditions are different, the difficulty of intelligent construction is not the same, we must adapt to local conditions, continue to improve the level of intelligent construction of coal mines

At present, China has initially formed different types of production of coal mine intelligent construction mode。In the single mine construction，It has formed a large-scale modern coal mine intelligent construction mode, which includes mining machine transportation, main and auxiliary industries, operation and management, and all aspects of underground surface intelligence，The intelligent construction mode of "intelligent disaster prevention system priority and other systems synchronous construction" in coal mines with serious disasters，And the intelligent construction mode of small and medium-sized coal mines with complex geological conditions is "emphasizing practicality and seeking practical results"。In terms of the construction of group mines, the National Energy Shendong Coal Group has explored the intelligent construction mode of the overall planning of mining areas and the integration of group mines on the basis of summarizing the experience of intelligent construction of single mines。Some coal-producing cities (counties) have concentrated on building intelligent coal mine demonstration areas, which has helped to improve the level of intelligent coal mine construction in the whole region。

2023年，The National Energy Administration released a compilation of Typical Cases of intelligent Coal Mine Construction in China (2023).，This paper summarizes the typical achievements of coal mining, excavation, main transportation, auxiliary transportation, network communication, power supply, water supply and drainage, inspection, auxiliary operation, sorting, coal blending and other aspects in the intelligent construction of coal mines in recent years，It provides a basis for the popularization and application of intelligent advanced technology achievements。The "Notice" clearly proposes to innovate the intelligent construction model, accelerate the promotion of the mature scheme recommended by the "National Collection of Typical Cases of intelligent Coal mine Construction (2023)", and explore and apply the intelligent construction model suitable for the region and the enterprise according to local conditions。The "Notice" also clarified the key construction content of mine, open-pit coal mine and coal preparation plant，In particular, it is required that the evaluation results of Jinggong coal mine meet the Class I construction conditions to encourage construction in accordance with intermediate and above standards，Those who meet the construction conditions of Class II and III are encouraged to carry out construction in accordance with primary and above standards，It provides guidance for classification iteration to promote the intelligent construction of coal mine and coal preparation plant。

Third, in view of the insufficient stable and reliable operation of the existing intelligent system, it is required to continuously improve the quality of operation and maintenance and management level, and promote the transformation of intelligent construction from technology-based to technical management, and from "building well" to "using well"

Summarizing the experience of intelligent construction in the past few years, only by realizing the normal operation of each intelligent system can we really promote the intelligent construction to go deep and solid;Only the real operation practice can lead the normal scenario needs, in order to improve the reliability of intelligent equipment and the adaptability to complex conditions。At present, the operation quality of many coal mine intelligent systems is not high, which is due to the short time of intelligent system completion, the lack of intelligent operation and maintenance standards, and the lack of operation and maintenance personnel。To meet the needs of technology upgrading, it is necessary for coal production enterprises to establish an intelligent operation and maintenance team, break the traditional single-system operation and maintenance mode, develop scenario-oriented intelligent operation and maintenance, accelerate the development of intelligent individual equipment, intelligent equipment and other on-site operation and maintenance tools, and constantly improve the intelligent operation and maintenance capacity and level of coal mines。

The "Notice" pays attention to the "scenarialization and normalization" of intelligent construction, and gives clear requirements for improving the effectiveness of the normal operation of the system from the aspects of technology and management。The circular requires that the functional potential of the built system be fully tapped，Improve scenario-based application and on-site adaptability，At present, the key scenarios that can continue to improve and improve the level are given，Such as coal mining automatic cutting and following machine transfer, driving remote control cutting, open-pit coal mine truck unmanned formation operation, coal preparation plant automatic adding and loading。The "Notice" also encourages coal mining enterprises to set up intelligent professional operation and maintenance institutions, develop a normal operation management system, strengthen the evaluation of the effectiveness of normal operation, especially to strengthen the scheduling analysis and supervision and inspection of the construction and operation of intelligent systems, and reduce or cancel the intelligent assessment level for those that are not used or used。

Fourth, the intelligent coal mine reflects the main characteristics of the new quality productivity of "high-tech, high efficiency, high quality", it is necessary to continuously strengthen scientific and technological innovation, break through the key technical bottlenecks restricting the development of intelligent development, and promote the overall leap in the technical level of the industry

In recent years，Under the cooperation of all parties involved in production, university and research，Positive progress has been made in a series of key technologies, such as cooperative control of coal mining face, rapid tunneling of roadway, 5G communication for mining, robot-assisted operation, and unmanned driving of open-pit cards，Intelligent coal mining has realized the full coverage of fully mechanized mining and caving technology from thin coal seam, medium thick coal seam to thick coal seam，Yujialiang Coal Mine of National Energy and Yangcun Coal Mine of Shandong Energy have realized unmanned normal intelligent mining in the working face，It has effectively promoted the development of new scenarios and new formats of intelligent coal mines。However, at present, technical problems such as geological fine protection, intelligent excavation, and intelligent disaster prevention still need to be continuously tackled, and some working environment conditions on the site are still poor, seriously threatening the physical and mental health of miners, and many operating scenes still require a large amount of labor, which seriously restricts the effective play of intelligent construction。

The Notice emphasizes the highly integrated development of the new generation of information technology and coal production，It is required to continuously promote the development and application of high-precision mining sensors, controllers, and industrial basic software，Push the terminal equipment to load the autonomous and controllable operating system;Encourage qualified localities to build coal industry Internet platforms，Gradually realize the intelligent analysis and unified management of coal mine production, operation and management data。The Notice attaches great importance to the research and development and application of key technologies and equipment，It requires the comprehensive use of such methods as "unveiling the list" and "horse racing"，To guide coal mining enterprises and social forces to carry out scientific and technological research，Key breakthroughs in high-precision geological detection, coal and rock identification, collaborative control of working face equipment groups, intelligent complete sets of (semi-) continuous mining equipment, intelligent soldier equipment, auxiliary operation robots and other technical problems。

The intelligent construction of coal mine is a long-term systematic project, which not only requires concept update, technology iteration and management improvement, but also requires policy support, standards and talent guarantee

Coal mine intelligence is not only the improvement of coal productivity, but also promote the change of production relations, so that workers can be liberated from the dangerous and heavy working environment, so that labor data, intelligent, convenient。Although the intelligent construction of coal mine in China has achieved obvious results, there is also a mismatch between intelligent input and benefit, miners' satisfaction and intelligent application。Find out why，The intelligent construction of coal mine is still in the initial stage，Technological equipment and production mode are undergoing upgrading and transformation，The majority of practitioners' understanding of intelligence is also deepening，Especially in the process of transformation of intelligent coal mine from construction to application，The role of intelligent standards, policies and talent team construction is more prominent。

The Circular attaches great importance to standards, policies and talent protection，Combined with the National Energy Administration recently issued the "Coal mine intelligent standard System Construction Guide"，It is required to establish and improve the standard system of general intelligent foundation, production system, technical equipment, information foundation, operation and maintenance guarantee and management of coal mine，And research the establishment of coal equipment national standardization, coal mine intelligent industry standardization and other technical organizations;The corresponding supporting policies are given to the new coal mine and the production coal mine which carry out the intelligent construction，It also requires all coal-producing provinces to improve incentive policies，To study the establishment of special awards and subsidies，Strengthen the construction elements of intelligent coal mine projects。For the current lack of intelligent talent, the development channel is not smooth common phenomenon，"Notice" clearly requires to innovate intelligent talent introduction, training, selection methods，Improve the classification of occupations in the coal industry，Formulate post configuration and professional skill level standards for intelligent inspection, operation and maintenance, centralized control, monitoring, communication, network, and data engineers，In particular, coal mining enterprises are encouraged to set up professional positions such as intelligent equipment engineers and operation and maintenance technicians，We will improve the salary distribution system。
